RAFFLE WALL FOE FURNACES. 1

Application filed August 24, 1920.

To aZZ whom it may concern:

Be it known that I, HELEODORO CANTI'I, a citizen of Mexico, residing at Baton Rouge, in the parish of East Baton Rouge and State of Louisiana, have invented new and useful improvements in Baffle lValls for Furnaces, of which the following is a speciiicatlon.

This invention relates'to furnace construction, particularly to furnaces in wh ch bo ler tubes are provided, and has for its ob ect the provision of a battle wall structure formed of a plurality of interfitting blocks or bricks which interlock so that the wall formed thereby will be very substantial and cannot be taken down except by beginnlng at the .top and successively removing the locking bricks.

An important object is the provision of a wall structure of this character which may be built up in connection with boiler tubes. several blocks being provided which have interfitting engagement with the tubes even though the tubes be inclined and in this latter event the inclination of the tubes Wlll serve to prevent downward displacement of the tube engaging blocks or bricks.

An additional object is the provision of a wall construction formed of specially constructed bricks which will be simple and inexpensive in manufacture, efficient in use, easy to assemble, durable in servlce, and a general improvement in the art.

With the above and other objects and advantages in View, the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawlngs in which Figure 1 is a cross sectional view through a furnace showing a front elevation of a baflie wall constructed in accordance with my invention,

Figure 2 is a longitudinal sectional view,

Figure 3 is a perspective view of one of the brick members,

Figure 1 is a perspective view showing one side of another brick member,

Figure 5 is a perspective view showing the other side thereof, and

Figure 6 is a perspective view of the third brick member.

Referring more particularly to the drawings, the letter A designates a furnace in which it is desired to construct a bafile wall and B designates the boiler tubes. In carry- Serial No. 405,672.

ing out my invention I provide different bricks 10, 11 and 12, from which the wall is constructed. The bricks 10 are relatively large and are formed rectangular in shape with the lower corners cut away, as shown at 13, and having the ends of its upper side snnilarly recessed or cut away, as shown at 14, the recesses 14 being double the width of the cut away portions 13 for a purpose to be described. In order to provide for accommodation of the tubes B, each brick 10 has one end formed with an arcuate recess 15 and has the opposite ends of its opposite side or face formed with arcuate recesses 16 of half the dimensions of the recess 15.

The brick 11 has a plain rectangular body of the same length as the brick 10 but of greatly less width and this brick 11 carries at its edges projections or lugs 17 adapted to fit within the recesses 13 or 14, as the case may be.

The brick 12 is relatively small and is designed to be used between successive bricks 11 and this brick 12 is formed with an arcuate cut away portion 18 adapted to cooperate with the recess 15 for conforming engagement with the tube.

In the construction of a bafiie wall from bricks, I employ a foundation of ordinary bricks C upon which are placed bricks 19 formed with recesses 20. Upon the bricks 19 I provide a series of the bricks l1 eX- tending transversely of the furnace and arranged on edge with the lugs 17 at their lower edges engaged within the recesses 20. Superposed upon the bricks 11 are the bricks 10 which have the mating recesses 13 on their undersides fitting upon the lugs 17 at the top of the bricks 11. The recesses 15 are disposed above the boiler tubes B. The blocks or bricks 12 are then disposed in position with the recesses 18 therein disposed upwardly and engaging against the bottoms of the tubes B and these bricks 12 fit between the successive bricks 11. The next row is formed by placing a series of the bricks 11 u on the row of bricks 10 just laid with the ugs 17 at the lower edges engaging within the recesses 1 1 in the tops of the bricks 10 just laid and in this way the joints are staggered, as is the common practice in masonry construction. In this second row of bricks 10 it will be observed that the arcuate recesses 16 of adjacent bricks 10 cooperate to conformingly engage the tubes B. This construction is continued until the entire wall is built and when this is done it will be observed that all the bricks have interlocking engagement by'means 01. the inter-fitting lugs and recesses so that the wall cannot be broken down except by startexpensive means for constructing a battle wall within a furnace, the parts of which are interlocking, the brick members all having conforming engagement with the boiler tubes which will consequently operate to prevent separation of the bricks.

While I have shown and described the preferred embodiment 01 my invention, it is of course to be understood. that I reserve the right to make such changes in the form, construction, and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. A. baiile wall construction for furnaces comprising a plurality of rectangular bricks arranged in a horizontal row and formed at the corners 01 their lower sides with cut away portions which mate on adjacent bricks to define recesses, a series or rectangular bricks arranged under said row of bricks in edgewise position and beneath the joints therebetween, lugs formed on the edges of said second named bricks-adjacent the ends thereof and fitting within the re rat teas cesses in the first named bricks, and successive rows of the first named bricks alternating with successive rows of the second named bricks, said first named bricks being tormed in their upper sides at the centers of their end portions with recesses receiving the lugs of the second named bricks of the row next above, and filler bricks between successive second named bricks.

2. A baffle wall construction for furnaces comprising alternating rows of horizontally disposed bricks and vertical bricks, the horizontal bricks having their corners of their lower sides cut away with said cut away portions of adjacent ones mating to form recesses, lugs -formed on the vertical bricks engaged within said recesses, said first named bricks being formed on their upper sides at the central portions of the ends with other recesses receiving the lugs 0n the row of vertical bricks thereabove, said horizontal bricks being formed in their under surfaces centrally off one end portion with inclined areuate recesses and being formed at the opposite corners of their ends on their upper faces with arcuate recesses adapted to mate for forming curved recesses, the sets of arcuate recesses conformingly receiving the boiler tubes of the furnace, and filler bricks disposed between suc' cessive vertical bricks and formed with areuate recesses cooperating with the otheri, arcuate recesses likewise for conforming en gagement with the boiler tubes. 7

In testimony whereof I affix my signature.
